Hundreds of hours, perhaps. But not for the entire life of the engine. If a modern passenger car engine could put out 200 hp nonstop for years on end, every semi-truck manufacturer would be putting a BMW engine in it, instead of a huge cast iron Cummins. But I'm pretty sure you'd spin a bearing, or wear out the cylinder liner, or burn a valve.
- throwaway0a5e 6y agoIf you tuned a semi engine for peak power the way automotive engines are they wouldn't last 400k either. You can get automotive engines with similar power to weight or power to displacement numbers as semi truck engines. They're just normal automotive engines sold for industrial use.
